Het item werd toegevoegd aan uw offerteaanvraag
Product Information
The Lenze EVF9329-EVV004 is a 45 kW frequency inverter from the 9300 Vector series designed for precise three-phase AC motor control in demanding industrial environments. Delivering a continuous rated output current of 89 A over an input supply range of 320 to 528 V AC, this drive supports flexible control modes including open-loop V/f, sensorless vector, and closed-loop vector control with encoder feedback. As a V004 variant, the unit is constructed without an internal radio interference filter, allowing machine builders and system integrators to implement external EMC filtering matched to specific cabinet and installation requirements.
Control and network integration are facilitated through plug-in terminal blocks and dedicated interface options. The inverter features an integrated CANopen system bus on terminal block X4 for drive networking at speeds up to 500 kbit/s, along with a plug-in Automation Interface slot that accepts expansion cards for fieldbus protocols such as PROFIBUS-DP, DeviceNet, INTERBUS, and EtherCAT. Control connections include 5 digital inputs, 2 digital outputs, 2 analog inputs, and 2 analog outputs, alongside motor thermal protection terminals and a relay output. When swapping or commissioning a replacement drive, parameter settings must be transferred to mirror the original application. The inverter stores up to four complete parameter sets in non-volatile EEPROM memory, which can be configured or loaded using Lenze Global Drive Control software or a Keypad XT unit. ABC Industrial Parts can assist in sourcing and preparing replacement units to ensure seamless system integration.
System status and operating faults are communicated directly through front-panel LEDs and diagnostic interfaces. Three status LEDs indicate state: a green LED for RUN status, a red LED for TRIP fault conditions, and a yellow LED indicating warning thresholds for current, voltage, or thermal limits. Detailed fault codes such as OC1 short-circuit detection, OU overvoltage, or OH heatsink overtemperature can be monitored via the Keypad XT module, the Global Drive Control online diagnostic window, or the internal fault history log. Initial troubleshooting should verify supply voltage across line terminals, motor insulation, control terminal connections, and cooling airflow across the heatsink. If internal hardware faults such as H05 or EEPROM communication errors occur, board-level failures are not field-serviceable, making drive repair or a tested exchange unit from ABC Industrial Parts the quickest route back to production.

Programming and Configuration
Parameter management for the Lenze EVF9329-EVV004 frequency inverter is executed through dedicated hardware tools and software engineering utilities. Drive parameterization can be performed directly at the cabinet using the plug-in Keypad XT (EMF2171IB) or remotely via a PC connection using Lenze Global Drive Control (GDC) software and a PC System Bus Adapter (EMF2177IB). Keypad XT provides clear display readouts and full parameter menu access for rapid commissioning, setpoint adjustments, and diagnostic monitoring without requiring a computer.
The inverter incorporates non-volatile EEPROM memory capable of holding four complete internal parameter sets. These parameter sets store motor calibration curves, control mode selections, I/O terminal assignments, acceleration ramps, and fieldbus configuration settings. During machine setup, multiple parameter sets allow pre-configured operational profiles for different products or operating modes, while providing an internal backup that preserves drive configuration during power outages.
When replacing a unit in the field, parameter sets can be uploaded from an existing drive or backup file via Global Drive Control software and downloaded into the replacement unit. Ensuring that motor data and operational parameters match the original drive profile is essential for maintaining dynamic vector performance and preventing trip conditions upon restart.
Communication and System Integration
The EVF9329-EVV004 provides comprehensive fieldbus and system networking capabilities to integrate into automated control systems. Standard drive-to-drive communication and parameterization are managed via an integrated CANopen system bus interface accessible on terminal block X4. Operating at transmission speeds up to 500 kbit/s, the CANopen bus allows fast cross-communication between Lenze drives and centralized PLC masters.
For integration into broader industrial automation networks, the drive features a dedicated plug-in Automation Interface (AIF) slot. This expansion slot accommodates modular fieldbus communication cards, including the Lenze PROFIBUS Module (EMF2133IB) and Lenze EtherCAT Module (EMF2192IB), as well as option modules for DeviceNet and INTERBUS. Installing an AIF module enables seamless cyclic control and direct parameter access over plant-wide fieldbus networks without modifying the core drive hardware.
Local control wiring connects through plug-in terminal blocks designed for rapid wiring and maintenance. The interface provides 5 digital inputs, 2 digital outputs, 2 analog inputs, and 2 analog outputs. Dedicated connections are also provided on terminal block X5 for a TRIP relay contact and on terminal X10 for motor thermal monitoring using PTC sensors or thermal contacts.
Diagnostics and Status Indication
Visual status indication on the front panel of the EVF9329-EVV004 allows immediate assessment of operational state and active faults. Three status LEDs convey drive conditions: a green LED (RUN) indicates ready, enabled, or initializing states; a red LED (TRIP) signals an active fault or trip condition; and a yellow LED alerts operators when current, voltage, or thermal warning thresholds have been reached.
Advanced diagnostic functionality is accessible using the optional Keypad XT or via the Global Drive Control (GDC) online diagnostic window. The drive maintains an internal non-volatile fault history log that records trip conditions for post-fault analysis. Additionally, hardwired fault signalling is supported through the potential-free TRIP relay contact output on terminal block X5, which can trigger emergency stop circuits or upstream controller alarms.
Status LED Indicators
| LED | Color/Status | Meaning |
|---|---|---|
| Green LED (RUN) | Green - Solid / Flashing | Solid = drive ready or operating; Flashing = drive enabled or initializing |
| Red LED (TRIP) | Red - Solid / Flashing | Drive trip or active fault condition |
| Yellow LED | Yellow - Solid | Warning or operating limit reached (current, voltage, or thermal threshold) |
Replacement and Spare Part Considerations
When replacing an existing drive with a Lenze EVF9329-EVV004, it is crucial to verify the exact variant suffix. The V004 specification designates a hardware variant engineered without an internal radio interference filter. If the existing installation relies on an external RFI line filter, ensure that the external filter remains installed and operational. Installing a V004 drive in a system expecting an integrated EMC filter without external filtering may cause electromagnetic interference issues.
Before placing a spare drive into service, the parameter set from the original unit must be loaded into the new inverter. Transferring parameters can be accomplished by saving the parameter set to a PC via Global Drive Control software using the PC System Bus Adapter (EMF2177IB) or transferring saved sets via the Keypad XT module. If an optional fieldbus communication card (such as PROFIBUS EMF2133IB or EtherCAT EMF2192IB) is present, transfer the card from the original unit to the plug-in AIF slot and verify node address settings.
Physical replacement involves verifying power input line voltages (320 to 528 V AC) and ensuring proper output phase sequence to the motor. Inspect plug-in control terminals for secure seating and verify that thermal protection wiring on terminal X10 and trip relay connections on terminal X5 are correctly terminated.
